SPRING-WHEEL.

' To all-whom it may concern Be it known that I, VINGENZO'MANCINI, a subject of the King. of Italy, residing at Schenectady, county of Schenectady, and

State of New York, have invented certain" new and useful Improvements in Springv I Wheels, of which the following is a specifi cation.

' ing drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several figures therein.

Figure 1 of the drawings is a view in side elevation of a spring-wheel embodying one form of my invention, the wheel being partly broken away and shown partly in vertical section for convenience of illustration. Fig. 2 is asimilar view of a spring-wheel embodying another form of my invention. Fig. 3 is a central cross-section of the wheel shown in Fig. 1. Fig. 4. is a plan view of a broken-away portion of the rim forming part of the central-body of the wheel shown 1n Fig. 1.. Fig. 5 is a plan view of the hub of the wheel shown in Fig. 1.- Fig. 6 is a for connecting the rigid spokes with the rim of the central bodyof the wheel shown in Fig. 1. Fig. 7 is a similar view of the same showing the rocker-slideway and the seat therefor in position upon said socket-plate.

.Fig. 8 is a central cross-section of the wheel shown in Fig. 2. Fig. 9 is a broken-away portion of the inner rim of the same. Fig. 10 is a plan view of the hub of the same. Fig. 11 is a plan view of a spoke-socket plate of the same.

The principal object of the invention is to produce a simple and eilicient spring-wheel.

Other objects will appear in connection with the following description,

Referring to Figs. 1 and 3 to 7 inclusive of the drawings, 1 is'a rigid'outer rim of circular form which may be provided with a solid'rubber or other tire, 2. v

The central body of the wheel comprises a hub, 3, an inner rim, 4, concentric with the hub, and rigid spokes, 5, connecting together said'hub and inner rim. The rigid spokes,

5, are mounted in pairs around the hub as shown in Figs. 1- and 3, each spoke'being' screwed at its inner end into the hub andat Patented Nov. 18, 1913.

its outer end into a socket-plate, 6, rigid-1y attached by bolts, 7 to the inner side of the inner rim, 4. Each pair of spokes, 5, forms a pair of guides for a sliding split box, 8, with which is pivotally connected the inner end, 9, of a slide-member, 10, the outer end of which is pivotally connected at 11 with the outer rim, 1.

The inner rim is provided with circumferential slots, 12, through which the respective slide-members,-10, extend, said slots bemg so formed that the inner, rim, 4, afl ords lateral support to the members, 10, butp'ermits them to have a limited movement in a plane at right angles to the axis of the permit the necessary movement of, the slidemember, 10, and 'with alongitudinal slideway, 14, adapted to receive a sliding rockerseat, 15, for a rocker slideway, 16, adapted to receive and closely confine the slide-member, 10, in its sliding movement.

The rocker-seat, 15, is connected by resilient rods, 17, with the hub, 3, said rodsbeing adapted to yicldingly support the respective rocker-seats, 15, with the slide-members, 10, extending in radial lines and. the outer rim, 1, concentric with the axis of the wheel.

Each rocker-slideway, 16, is in the form of a. middle segment of a circular disk, provided with a slideway aperture, 18, for the member, 10; and the rocker-seat, 15,*is of similar circular form so that when the rocker-slideway has been inserted endwise into the seat and then turned to bring its aperture, 18, into position to receive the member, 10, the rocker-slideway will be re-' taincd by the seat with freedom to rock thereon. p

The rods, 17, are formed in pairs connected together at their inner ends, the inno! end of each pair being inserted within an opening, 20, in the hub, 3, and held therein by a screw-bolt, 19.

The inner rim is provided with apertures, 21, alternating with the slots, 12, through which apertures, 21, the rods, 17, can be inserted or removed in pairs.

' gles to the axis of thewheel.

*bers,

The resilient rods, 17, constitute springmembers which act through the slide-mem- 10, to yieldingly maintain the rim concentric with the axis of the wheel.

When the wheel is under load, as shown in Fig. 1, the outer rim, 1, is forced upward relatively to the central body of the wheel causing such-of the rods, 17, as are not substantially vertical, to bend more or less in response to, while yieldingly resisting, the movement of the slide-members, 10.

As the wheel rolls along the roadway un-' the inner rim, 4. Each slide-member, 10, is

pivotally connected at its inner end to a slide-block, 24, confined within a spoke, 22, in engagement with a coil-spring, 25, which tends to force the block, 24, outward. The slide-member,' 10, passes through a rockerslideway, 26, having trunnions, 27 rotatively mounted in the outer ends of a pair of resilient rods, 28, the inner ends of which rods are rigidly connected to the hub, 3, by means of a screw-bolt, 29, and a pair of lugs, 30, on the hub between which each resilient rod is closely confined. The base of the socket, 23, is formed with slots, 31, adapted to freely receive the respective trunnions, 27, and permit a limited movement of the rocker-slideways, 26, in a plane at right an- In this con- 25, assist the resilient rods, 28,. in tending to maintain the outer rim, 1, concentric with the axis of the wheel.

What I claim as new and desire to secure by Letters Patent is- 1. A spring-wheel comprising a central body, a rim encircling said central body, slide-members severally having a connection with said rim, and a pivotal connection with said body capable of movement toward and from'the center thercofi rockcr-slidcways for the respective slidemembers mounted in connection with said, central body with freedrm for limited reciprocating movement in a plane at right angles to the axis of the wheel, and spring-members acting through said siidcmembers toyicldingly maintain the rim concentric with the axis of the wheel A spring-wheel comprisinga' ccnlrul body a rimencircling said central body. slide-members severally having a connection with said rim, and a pivotal connection with struction the coil-springs,

said body capable of movement toward and from the center thereof, rocker-slideways for the respective slide-members mounted in connection with said central body with freedom for limited reciprocating movement in a plane at right angles to the axis of the wheel, and spring-members opposed to said reciprocating movement of said rocker slideways.

3.
